Is it unholy to eat pork due to the passages in the King James version of the bible? Are there any verses that state that pork is okay to eat?
There are verses in the Bible which tell us that the Old Testament food requirements are no longer applicable nor is it wrong to consume food that has been associated with “sin” (idolatry, false religion) unless is causes a fellow Christian to stumble.
Concerning the removal of dietary constraints (all foods are now permissible; there are no “unclean” foods):
Acts 10:9-16 The next day, as they went on their journey and drew near the city, Peter went up on the housetop to pray, about the sixth hour. Then he became very hungry and wanted to eat; but while they made ready, he fell into a trance and saw heaven opened and an object like a great sheet bound at the four corners, descending to him and let down to the earth. In it were all kinds of four-footed animals of the earth, wild beasts, creeping things, and birds of the air. And a voice came to him, “Rise, Peter; kill and eat.” But Peter said, “Not so, Lord! For I have never eaten anything common or unclean.” And a voice spoke to him again the second time, “What God has cleansed you must not call common.” This was done three times. And the object was taken up into heaven again. (NKJV; emphasis mine)
Concerning food that is associated with a worldly or sinful practice:
1 Corinthians 8:1-13 Now concerning things offered to idols: We know that we all have knowledge. Knowledge puffs up, but love edifies. And if anyone thinks that he knows anything, he knows nothing yet as he ought to know. But if anyone loves God, this one is known by Him. Therefore concerning the eating of things offered to idols, we know that an idol is nothing in the world, and that there is no other God but one. For even if there are so-called gods, whether in heaven or on earth (as there are many gods and many lords), yet for us there is one God, the Father, of whom are all things, and we for Him; and one Lord Jesus Christ, through whom are all things, and through whom we live. However, there is not in everyone that knowledge; for some, with consciousness of the idol, until now eat it as a thing offered to an idol; and their conscience, being weak, is defiled. But food does not commend us to God; for neither if we eat are we the better, nor if we do not eat are we the worse. But beware lest somehow this liberty of yours become a stumbling block to those who are weak. For if anyone sees you who have knowledge eating in an idol’s temple, will not the conscience of him who is weak be emboldened to eat those things offered to idols? And because of your knowledge shall the weak brother perish, for whom Christ died? But when you thus sin against the brethren, and wound their weak conscience, you sin against Christ. Therefore, if food makes my brother stumble, I will never again eat meat, lest I make my brother stumble. (NKJV; emphasis mine)
1 Corinthians 10:23-33 All things are lawful for me, but not all things are helpful; all things are lawful for me, but not all things edify. Let no one seek his own, but each one the other’s well-being. Eat whatever is sold in the meat market, asking no questions for conscience’ sake; for “the earth is the Lord’s, and all its fullness.” If any of those who do not believe invites you to dinner, and you desire to go, eat whatever is set before you, asking no question for conscience’ sake. But if anyone says to you, “This was offered to idols,” do not eat it for the sake of the one who told you, and for conscience’ sake; for “the earth is the Lord’s, and all its fullness.” “Conscience,” I say, not your own, but that of the other. For why is my liberty judged by another man’s conscience? But if I partake with thanks, why am I evil spoken of for the food over which I give thanks? Therefore, whether you eat or drink, or whatever you do, do all to the glory of God. Give no offense, either to the Jews or to the Greeks or to the church of God, just as I also please all men in all things, not seeking my own profit, but the profit of many, that they may be saved. (NKJV; emphasis mine)
